Abstract The present work aims at the fabrication and mechanical & shape recovery performances of a graphene-poly(styrene-co-butyl acrylate) composite. First, the graphene oxide was prepared by Hummers method, and then reduced by using hydrazine hydrate to prepare graphene. Secondly, the graphene and isocyanate-treated graphene were separately added into a mixed solution containing styrene and butyl acrylate which served as monomers, and a free radical polymerization process was employed to fabricate a series of shape memory composites (graphene-poly(styrene-co-butyl acrylate)) differed in graphene content. We then characterized and estimated the shape memory composites’ performances by applying DMA test and mechanical properties tests, and the results indicated that both the additions of graphene and isocyanate-treated graphene contribute to the declines of both storage modulus and glass transition temperature of the shape memory composites. An inverse correlation between graphene content and tensile modulus of the composites was also observed. At the same temperature, the shape recovery capability of the composites fabricated with isocyanate-treated graphene is generally better than that with untreated graphene (under equal graphene content).
